16.1 Overview
Spatial interaction represent the flow of people, material, or information between locations in geographical space. It encompasses everything from freight shipments, energy flows, and the global trade in rare antiquities, to flight schedules, rush hour woes, and pedestrian foot traffic. Understanding what factors and logic went into the decision-making behind those human-induced movements and interdependencies is important because it enables policy makwers to better understand, predict, manage, and help plan for such circulation. For example, policy makers can make informed decisions about how to better allocate resources to improve traffic in a city or to speed up shipments of perishable foodstuffs. It has to do with having a good understanding of the overall situation.
Spatial Interaction Models (SIMs) are mathematical models for estimating movement between spatial entities developed by Alan Wilson in the late 1960s and early 1970, with considerable uptake and refinement for transport modelling since then Boyce and Williams (2015). There are four main types of traditional SIMs (Wilson 1971): - Unconstrained - Production-constrained - Attraction-constrained - Doubly-constrained
Both ordinary least square (OLS) and negative binomial (NB) regression methods have been used extensively to calibrate OD flow models by processing flow data as different types of dependent variables.
16.2 Getting Started
For the purpose of this exercise, four r packages will be used. They are:
- sf for importing, integrating, processing and transforming geospatial data.
- tidyverse for importing, integrating, wrangling and visualising data.
- tmap for creating thematic maps.
16.3 Preparing the Flow Data
16.3.1 Importing the OD data
Firstly, we will import the Passenger Volume by Origin Destination Bus Stops data set downloaded from LTA DataMall by using read_csv() of readr package.
odbus <- read_csv("chap15/data/aspatial/origin_destination_bus_202210.csv")Let use display the odbus tibble data table by using the code chunk below.
glimpse(odbus)Rows: 5,122,925
Columns: 7
$ YEAR_MONTH <chr> "2022-10", "2022-10", "2022-10", "2022-10", "2022-…
$ DAY_TYPE <chr> "WEEKDAY", "WEEKENDS/HOLIDAY", "WEEKENDS/HOLIDAY",…
$ TIME_PER_HOUR <dbl> 10, 10, 7, 11, 16, 16, 20, 7, 7, 11, 11, 8, 11, 11…
$ PT_TYPE <chr> "BUS", "BUS", "BUS", "BUS", "BUS", "BUS", "BUS", "…
$ ORIGIN_PT_CODE <dbl> 65239, 65239, 23519, 52509, 54349, 54349, 43371, 8…
$ DESTINATION_PT_CODE <dbl> 65159, 65159, 23311, 42041, 53241, 53241, 14139, 9…
$ TOTAL_TRIPS <dbl> 2, 1, 2, 1, 1, 4, 1, 3, 1, 5, 2, 5, 15, 40, 1, 1, …A quick check of odbus tibble data frame shows that the values in OROGIN_PT_CODE and DESTINATON_PT_CODE are in numeric data type. Hence, the code chunk below is used to convert these data values into character data type.
odbus$ORIGIN_PT_CODE <- as.factor(odbus$ORIGIN_PT_CODE)
odbus$DESTINATION_PT_CODE <- as.factor(odbus$DESTINATION_PT_CODE) 16.3.2 Extracting the study data
For the purpose of this exercise, we will extract commuting flows on weekday and between 6 and 9 o’clock.
odbus6_9 <- odbus %>%
filter(DAY_TYPE == "WEEKDAY") %>%
filter(TIME_PER_HOUR >= 6 &
TIME_PER_HOUR <= 9) %>%
group_by(ORIGIN_PT_CODE,
DESTINATION_PT_CODE) %>%
summarise(TRIPS = sum(TOTAL_TRIPS))Table below shows the content of odbus6_9
datatable(odbus6_9)We will save the output in rds format for future used.
write_rds(odbus6_9, "chap15/data/rds/odbus6_9.rds")The code chunk below will be used to import the save odbus6_9.rds into R environment.
odbus6_9 <- read_rds("chap15/data/rds/odbus6_9.rds")16.4 Working with Geospatial Data
For the purpose of this exercise, two geospatial data will be used. They are:
- BusStop: This data provides the location of bus stop as at last quarter of 2022.
- MPSZ-2019: This data provides the sub-zone boundary of URA Master Plan 2019.
Both data sets are in ESRI shapefile format.
16.4.1 Importing geospatial data
Two geospatial data will be used in this exercise, they are:

st_read()function of sf package is used to import the shapefile into R as sf data frame.st_transform()function of sf package is used to transform the projection to crs 3414.
16.5 Geospatial data wrangling
16.5.1 Combining Busstop and mpsz
Code chunk below populates the planning subzone code (i.e. SUBZONE_C) of mpsz sf data frame into busstop sf data frame.
busstop_mpsz <- st_intersection(busstop, mpsz) %>%
select(BUS_STOP_N, SUBZONE_C) %>%
st_drop_geometry()
Note
st_intersection()is used to perform point and polygon overly and the output will be in point sf object.select()of dplyr package is then use to retain only BUS_STOP_N and SUBZONE_C in the busstop_mpsz sf data frame.- five bus stops are excluded in the resultant data frame because they are outside of Singapore bpundary.
datatable(busstop_mpsz)Before moving to the next step, it is wise to save the output into rds format.
write_rds(busstop_mpsz, "chap15/data/rds/busstop_mpsz.rds") Next, we are going to append the planning subzone code from busstop_mpsz data frame onto odbus6_9 data frame.
od_data <- left_join(odbus6_9 , busstop_mpsz,
by = c("ORIGIN_PT_CODE" = "BUS_STOP_N")) %>%
rename(ORIGIN_BS = ORIGIN_PT_CODE,
ORIGIN_SZ = SUBZONE_C,
DESTIN_BS = DESTINATION_PT_CODE)Before continue, it is a good practice for us to check for duplicating records.
duplicate <- od_data %>%
group_by_all() %>%
filter(n()>1) %>%
ungroup()If duplicated records are found, the code chunk below will be used to retain the unique records.
od_data <- unique(od_data)It will be a good practice to confirm if the duplicating records issue has been addressed fully.
Next, we will update od_data data frame cwith the planning subzone codes.
od_data <- left_join(od_data , busstop_mpsz,
by = c("DESTIN_BS" = "BUS_STOP_N")) duplicate <- od_data %>%
group_by_all() %>%
filter(n()>1) %>%
ungroup()od_data <- unique(od_data)od_data <- od_data %>%
rename(DESTIN_SZ = SUBZONE_C) %>%
drop_na() %>%
group_by(ORIGIN_SZ, DESTIN_SZ) %>%
summarise(MORNING_PEAK = sum(TRIPS))It is time to save the output into an rds file format.
write_rds(od_data, "chap15/data/rds/od_data.rds")od_data <- read_rds("chap15/data/rds/od_data.rds")16.6 Visualising Spatial Interaction
In this section, you will learn how to prepare a desire line by using stplanr package.
16.6.1 Removing intra-zonal flows
We will not plot the intra-zonal flows. The code chunk below will be used to remove intra-zonal flows.
od_data1 <- od_data[od_data$ORIGIN_SZ!=od_data$DESTIN_SZ,]16.6.2 Creating desire lines
In this code chunk below, od2line() of stplanr package is used to create the desire lines.
flowLine <- od2line(flow = od_data1,
zones = mpsz,
zone_code = "SUBZONE_C")16.6.3 Visualising the desire lines
To visualise the resulting desire lines, the code chunk below is used.
tm_shape(mpsz) +
tm_polygons() +
flowLine %>%
filter(MORNING_PEAK >= 5000) %>%
tm_shape() +
tm_lines(lwd = "MORNING_PEAK",
style = "quantile",
scale = c(0.1, 1, 3, 5, 10),
n = 5,
alpha = 0.3)
Warning
Be patient, the rendering process takes more time because of the transparency argument (i.e. alpha)

In this section, you will learn how to calibrate Spatial Interaction Models by using Poisson Regression method.
16.13.1 Importing the modelling data
Firstly, let us import the modelling data by using the code chunk below.
SIM_data <- read_rds("chap15/data/rds/SIM_data.rds")16.13.2 Visualising the dependent variable
Firstly, let us plot the distribution of the dependent variable (i.e. TRIPS) by using histogram method by using the code chunk below.
ggplot(data = SIM_data,
aes(x = TRIPS)) +
geom_histogram()
Notice that the distribution is highly skewed and not resemble bell shape or also known as normal distribution.
Next, let us visualise the relation between the dependent variable and one of the key independent variable in Spatial Interaction Model, namely distance.
ggplot(data = SIM_data,
aes(x = dist,
y = TRIPS)) +
geom_point() +
geom_smooth(method = lm)
Notice that their relationship hardly resemble linear relationship.
On the other hand, if we plot the scatter plot by using the log transformed version of both variables, we can see that their relationship is more resemble linear relationship.
ggplot(data = SIM_data,
aes(x = log(dist),
y = log(TRIPS))) +
geom_point() +
geom_smooth(method = lm)
16.13.3 Checking for variables with zero values
Since Poisson Regression is based of log and log 0 is undefined, it is important for us to ensure that no 0 values in the explanatory variables.
In the code chunk below, summary() of Base R is used to compute the summary statistics of all variables in SIM_data data frame.

16.13.4 Unconstrained Spatial Interaction Model
In this section, you will learn how to calibrate an unconstrained spatial interaction model by using glm() of Base Stats. The explanatory variables are origin population by different age cohort, destination population by different age cohort (i.e. wj3_destmedinc) and distance between origin and destination in km (i.e. dist).
The general formula of Unconstrained Spatial Interaction Model
The code chunk used to calibrate to model is shown below:
uncSIM <- glm(formula = TRIPS ~

In order to measure how much variation of the trips can be accounted by the model we will write a function to calculate R-Squared value as shown below.
CalcRSquared <- function(observed,estimated){
r <- cor(observed,estimated)
R2 <- r^2
R2
}Next, we will compute the R-squared of the unconstrained SIM by using the code chunk below.

16.13.9 Model comparison
Another useful model performance measure for continuous dependent variable is Root Mean Squared Error. In this sub-section, you will learn how to use compare_performance() of performance package
First of all, let us create a list called model_list by using the code chun below.
model_list <- list(unconstrained=uncSIM,
originConstrained=orcSIM,
destinationConstrained=decSIM,
doublyConstrained=dbcSIM)Next, we will compute the RMSE of all the models in model_list file by using the code chunk below.
compare_performance(model_list,
metrics = "RMSE")# Comparison of Model Performance Indices
Name | Model | RMSE
-----------------------------------------
unconstrained | glm | 2429.978
originConstrained | glm | 2057.579
destinationConstrained | glm | 1891.724
doublyConstrained | glm | 1487.111The print above reveals that doubly constrained SIM is the best model among all the four SIMs because it has the smallest RMSE value of 1487.111.
16.13.10 Visualising fitted
In this section, you will learn how to visualise the observed values and the fitted values.
Firstly we will extract the fitted values from each model by using the code chunk below.
df <- as.data.frame(uncSIM$fitted.values) %>%
round(digits = 0)Next, we will join the values to SIM_data data frame.
SIM_data <- SIM_data %>%
cbind(df) %>%
rename(uncTRIPS = "uncSIM$fitted.values")Repeat the same step by for Origin Constrained SIM (i.e. orcSIM)
df <- as.data.frame(orcSIM$fitted.values) %>%
round(digits = 0)SIM_data <- SIM_data %>%
cbind(df) %>%
rename(orcTRIPS = "orcSIM$fitted.values")Repeat the same step by for Destination Constrained SIM (i.e. decSIM)
df <- as.data.frame(decSIM$fitted.values) %>%
round(digits = 0)SIM_data <- SIM_data %>%
cbind(df) %>%
rename(decTRIPS = "decSIM$fitted.values")Repeat the same step by for Doubly Constrained SIM (i.e. dbcSIM)
df <- as.data.frame(dbcSIM$fitted.values) %>%
round(digits = 0)SIM_data <- SIM_data %>%
cbind(df) %>%
rename(dbcTRIPS = "dbcSIM$fitted.values")unc_p <- ggplot(data = SIM_data,
aes(x = uncTRIPS,
y = TRIPS)) +
geom_point() +
geom_smooth(method = lm)
orc_p <- ggplot(data = SIM_data,
aes(x = orcTRIPS,
y = TRIPS)) +
geom_point() +
geom_smooth(method = lm)
dec_p <- ggplot(data = SIM_data,
aes(x = decTRIPS,
y = TRIPS)) +
geom_point() +
geom_smooth(method = lm)
dbc_p <- ggplot(data = SIM_data,
aes(x = dbcTRIPS,
y = TRIPS)) +
geom_point() +
geom_smooth(method = lm)
ggarrange(unc_p, orc_p, dec_p, dbc_p,
ncol = 2,
nrow = 2)
